1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

As a part of aging there are known to be numerous alterations which occur in multiple tissues of the body, and the focus of this study was to determine the extent to which oxidative stress and hypoxia occur during adipose tissue aging. In our studies we demonstrate for the first time that aging is associated with both hypoxia (38% reduction in oxygen levels, Po(2) 21.7 mmHg) and increases reactive oxygen species in visceral fat depots of aging male C57Bl/6 mice. Interestingly, aging visceral fat depots were observed to have significantly less change in the expression of genes involved in redox regulation compared with aging subcutaneous fat tissue. Exposure of 3T3-L1 adipocytes to the levels of hypoxia observed in aging adipose tissue was sufficient to alter multiple aspects of adipose biology inducing increased levels of in insulin-stimulated glucose uptake and decreased lipid content. Taken together, these data demonstrate that hypoxia and increased levels of reactive oxygen species occur in aging adipose tissue, highlighting the potential for these two stressors as potential modulators of adipose dysfunction during aging.
